Now you can have memory recall on your factory or aftermarket tach with our easy to install kit. Works with any electric tach and on your factory "electronic" tachometer. Simply connect the little black box in between your existing tach and the tach signal from your ignition.
The microprocessor monitors each incoming tach signal and saves the highest reading. In normal mode, the microprocessor simply sends the incoming tach signal straight to your tach, but when you press the button, the microprocessor recalls and send the highest signal to your tach instead of the one coming from the ignition. Simple.
